It should do this and it's not semantically different from what
happens with non-MBS disks. The log I pasted is what unmaps the
volume, I am not sure why it returned successfully if the volume
wasn't unmapped, if possible please attach vdsm and supervdsm logs
from the relevant, perhaps there's some clue there.
But we essentially use cinderlib's `disconnect`, so perhaps it hasn't errored
